ABSTRACT:
Dispensing containers are described in which a metering chamber for the contents of a fluid container is mounted in the neck of the container. Openings intermediate the height of the chamber allow it to be put in communication with the container interior by a rotary movement, e.g. applied to an external closure cap. When the closure cap is rotated to open the chamber to the container interior it also adopts a sealing position preventing the escape of any of the contents. The space in the chamber above the apertures is greater than that below. Sufficient fluid can be admitted to the chamber by inverting the container, therefore, to ensure that the lower space is completely filled when the container is again turned upright. Reverse rotation closes the openings to isolate the metered fluid from the main volume of the container and can also open the chamber to the exterior to allow the metered quantity to be dispensed.
